This is not directly about the question but just to clarify, UITextField and UILabel does not support opening URLs. If you want to use UILabel wi...

How to dismiss keyboard for UITextView with return key?
...Even then if you want to do this, implement the textView:shouldChangeTextInRange:replacementText: method of UITextViewDelegate and in that check if the replacement text is \n, hide the keyboard.
There might be other ways but I am not aware of any.

Odd behavior when Java converts int to byte?
...
byte in Java is signed, so it has a range -2^7 to 2^7-1 - ie, -128 to 127.
Since 132 is above 127, you end up wrapping around to 132-256=-124. That is, essentially 256 (2^8) is added or subtracted until it falls into range.
For more information, you may want t...
Conveniently Declaring Compile-Time Strings in C++
... constexpr char x = world[5]; // Does not compile because index is out of range!
}
It doesn't get much cooler than compile-time range checking!
Both the use, and the implementation, is free of macros. And there is no artificial limit on string size. I'd post the implementation here, but I'm re...
How to generate all permutations of a list?

A couple of alternative approaches are listed in the documentation of...

More elegant way of declaring multiple variables at the same time

@Zac to correctly do so use a, b, c = ([] for i in range(3)). source. For consistency, you could also use a variant of that for this answer, i.e., a,b,c,d,e,g,h,i,j = (True for i in range(9)) f=(False i in range(1)).

Split array into chunks
...
My preferred way nowadays is the above, or one of the following:
Array.range = function(n) {
// Array.range(5) --> [0,1,2,3,4]
return Array.apply(null,Array(n)).map((x,i) => i)
};
Object.defineProperty(Array.prototype, 'chunk', {
value: function(n) {
